UI Cheats Extension – Allows you to click on the UI and enter cheats directly.

Special whims for: pregnancy, elder life stage, childhood phases, etc.

Whim Overhaul – This is an overhaul of the EA whim system which enhances the chances for family based whims and tunes down whims to buy new stuff.

Simulation Unclogger – Detects when a Sim causes the simulation to get stuck, rendering the game unplayable, and attempts to fix it.

I use this instead of the Simulation Lag Fix because I find it works better in my game.

Quicker Sim Autonomy & Simulation Lag Improvements – You will need an account at Sims Asylum to download this mod.

MC Command Center – This is Master Controller for Sims 4.

Removes idle chat and makes several other improvements. For example, romance Sims are more likely to do romantic interactions and mean Sims are more likely to do mean interactions.

Have Some Personality Please – Adds more personality to your Sims.

Although I play with all the mods on this list, there are a few I could not EVER play without.
